A lever 10 enables a changeover from a mode of operation in which the table 16 is lowered during each cycle to a mode in which the table is moved forward in each slices so that the slices are stacked in an overlapping array. Rotation of knob 12, Fig. 5, rotates a screw spindle 64 to move a nut 65 thereby adjusting, by lever  linkages, the position of knife guard 7, the position of a lever 62 to determine the distance moved by clamp 9 in each cycle, and the position of a lever 84 which determines the distance that table 16 is lowered in each cycle. The knob 12 may allow stepless variation in slice thickness between 0À1 and 10 mm, and preferably between 0À5 and 8À5 mm.

Abstract: 1,187,188. Transmutation of elements. ATOMIC ENERGY OF CANADA Ltd. 31 Oct., 1968 [20 March, 1968], No. 51716/68. Heading G6P. In a process for the conversion of thorium 232 into uranium 233 by neutron irradiation, thorium oxide is positioned in an intense thermal neutron beam for a short period. The thorium 232 captures neutrons and is converted to thorium 233 which decays by a radio-active beta decay having a half life of 22À4 minutes to protoactinium 233. Irradiation is stopped and the protoactinium 233 decays by radioactive beta decay, half life 27 days, to fissile uranium 233. A portion of the protoactinium 233 produced during the irradiation captures neutrons and is converted to protoactinium 234 which decays to fertile uranium 234. Fissile 235 is also formed, by neutron capture, from the uranium 234.

Abstract: 1358167 Measuring intrinsic safety R J REDDING 29 Oct 1971 [3 Nov 1970] 52110/70 Heading G1U The intrinsic safety of a circuit 1, i.e., its inductance since this determines the size of the spark produced when current in the circuit is interrupted, is measured by first establishing a known current from a battery 4 through the circuit via a contact 7, and then opening the contact 7 and integrating, on a capacitor 8, the energy emitted by the circuit. The resulting potential on the capacitor 8 is then a measure of the inductance of the circuit 1 under test. A switch 11 may be closed to discharge the capacitor prior to a test. Different sizes of capacitor 8 may be selected by a switch 14, and a reference inductance 12 may be included in the circuit.

A coin-changing machine comprises a tube 5 for receiving a coin to be changed, tubes 3, 4, for receiving coins to be dispensed as change, an apertured slide 6 for feeding the coins to discharge openings 3<SP>11</SP>, 4<SP>11</SP> and 511, a member 19 sensing the presence of a coin in the tube 4, and a rotatable guide 24 having shoots 21, 22, 23, the shoot 22 being at right-angles to the shoots 21, 23, which is positioned under the control of member 19 to direct the coins as appropriate to a cash box 29 and return cup 30. The slide is reciprocated by a member 10 attached to a shaft 9. Movement of the member 10 is limited by a latch 14, cammed away from the member 10 when a coin in the tube 5 engages a pin 16 on the latch on initial movement of the slide. The guide 24 is urged counterclockwise by a spring 28 to bring a stop 25 on the guide against an abutment 27 fixed to the shaft 9. Simultaneously with movement of the abutment 27 clear of the stop 25 by rotation of the shaft 9, a pivoted member 18 moved into the path of an abutment 26 on the guide 24, through engagement of a coin in the tube 4 with an upstanding member 19 on the member 18, to hold the guide 24 stationary. In this position shoots 21, 23 direct the coins from tubes 3, 4 to a return cup 30 and shoot 22 disects the coin from tube 5 to a cash box 29. If the tube 4 is empty, the member 18 is unmoved whereby the guide rotates through 90 degrees to return the coin from tube 5 to the customer. Alternatively, the shoots 21-23 may be re-directed and the guide rotated through 90 degrees when a coin is detected in tube 4 and held stationary otherwise. The slide may feed more than one coin from a tube at a time.
